To all whom, it may concern:

Be it known that 1, ROBERT FISCHER, a citizen of the United States, anda resident of the city of New York, borough of Brooklyn, in the countyof Kings and State of New York, have invented a new and ImprovedPin-Retaining Device, of which the following is a full, clear, and exactdescription.

The purpose of the invention is to provide a very simple, economic, andeflective device for holding a pin in the position in which it maybeplaced in a fabric or garment until purposely removed by the wearer orother authorized person and to so construct the deyice that it will belight, simple, strong, and

easily operated to lock the pin or release it. The invention consists inthe novel construction and combination of the several parts, as will behereinafter fully set forth, and pointed out inthe claim.-

.Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1. is a perspective view of the device in locked position on apin. Fig. 2 is a longitudinal section through the device, drawn upon anenlarged scale, showing a portion of a pin therein in dotted lines. Fig.3 is a transverse section taken oracticall on the line 3 C3 of l. 2 andFig. i is a vertical tion through the device, showing the two .nainportions thereof partially separated.

The device is made in two sections A and B, suitably connected, thesection A being that which receives the pin, and the section B thatwhich contains the locking mechanism for the pin. Both sections areconstructed ol' thin sheet metal and are preferably substantiallyU-shaped in cross-section.

The outer longitudinal edge portion 11 of the pin-receiving section A isstraight and closed, while its inner longitudinal port ionis open, andthe edges 12 are inclined from the top downward relatively to the edgeportion 11 in a manner to render the lower portion of the said sectionwider. At *caoh inclined edge 12 an outwardly-extending marginal flange13 is formed; The said section A is provided with a top 14, that extendsbeyond the inclined edges 12 and at its projected portion is providedwith a downwardly-extendin'g guide-lip 15 ,'and at the outer straightedge 11 of said section A an aperture 15' is prov ded, through'which theshank 16 of a pin C is passed and likewise through a cprrespondingaperture. 17 in the bottom section 16 of said section.

The section B, containing the locking edges, being to that end providedat the edges of its inner longitudinal portion, which is open, withinwardly-extending flanges 18, that engage with the flanges 13 of thesection A, as shown in Fig. 3, whereby to prevent transverse separationof the sections when assembled. 1

The bottom of the section B is open; but its top is partially orentirely closed by a horizontal lip 19, and in the normal position ofthe said sections A and B the lip 19 of the section B lies close to thetop 14 of the see lion A, and the lip 15'- of the latter section is inengagement with the outer surface of the section B, as is shown in Fig.2. A spring 21,-preierably a coiled spring, is located within thesection B, having hearing at its lower end upon the bottom of thesection A and guiding contact with the inclined edges of said section A,which spring at its upper end supports a ball 22, holding said ballnormally close to the lip 19 of the section B, is also shown in Fig. Theball 22 enwith the inclined edges oi the section and when said ball inits upper or nor mal position it also so engages wits the shank its oithe pin 0 that when an attempt is made to withdraw the pin from thedevice without properly operating its sections such an. attempt willtend only to bind the device closer to the pin. tion is desired, it issimply necessary to draw down the section B, whereupon the ball travclsdown. the inclined edges of the section A, as is'shown in dotted linesin Fig. '2 and in l'ull lines in Fig. 4, and is carried away from theshank of the pin C, and the latter at such time may be quickly andconveniently withdrawn from the dr-lvice. W hen the section B isreleased, it returns to its normal position, and the device is again incondition. for looking engagement with a pin.

- The pin-carrying section A may be properly termed the bod y-sectionand the sliding section B a locking-section.

Having thus described. my invention, claim as new and desire to secureby Letters Patent A pin-retaining device, consisting of a body-scctionsubstantially U-shaped in. cross Wire-n, l'iowovci', a separa section,having a closed top and bottom and registering openings therein for thepassage of a pin, the longitudinal edges at the open portion of the saidbody-section being downwardly and outwardly inclined, a lockin sectionmounted to slide upon the body-section at its inclined portion, saidlockingsection being also substantially U-shaped in cross-section, itsouter longitudinal edge portion being its closed portion and saidlockingsection being provided with an open bottom and a substantiallyclosed top, the top of the locking-section being below the top of thebody-section, a guide-lip extending down from the to of the body-sectionin engagement with tlie outer edge portion of the locking-section, aball located within the locking section, adapted to travel upon theinclined (set-4,274

edges of the body-section, which ball when in the upper portion of thelocking-section being in position for engagement with a pin passedthrough the apertures in the bodysection, and a spring upon which saidball rests, the lower end of'the said spring bearing upon the bottom ofthe body-section, and an inner side portion of said spring havingbearing upon the inclinededges of the bodysection, for the purposedescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
